Developing an Output‐Oriented Super Slacks‐Based Measure Model with an Application to Third‐Party Reverse Logistics Providers

Outsourcing is an increasingly significant topic pursued via corporations seeking enhanced efficiency. Third‐party reverse logistics involves the employ of external firms to carry out some or all of the firm's logistics activities. Output‐oriented super slacks‐based measure (SBM) model is one of the models in data envelopment analysis (DEA). In many real‐world applications, data are often stochastic. A successful approach to address uncertainty in data is to replace deterministic data via random variables, leading to chance‐constrained DEA. In this paper, a chance‐constrained output‐oriented super SBM model is developed and also its deterministic equivalent, which is a nonlinear program, is derived. Furthermore, it is shown that the deterministic equivalent of the stochastic output‐oriented super SBM model can be converted into a quadratic program. In addition, sensitivity analysis of the stochastic output‐oriented super SBM model is discussed with respect to changes on parameters. Finally, a numerical example demonstrates the application of the proposed model. Copyright © 2011 John Wiley & Sons, Ltd.     

Talking about ‘Fairness’ in Football and Politics: The Case of Navad

ABSTRACT

We argue that sport in general, and association football in particular, are activities that invite spectators and players alike to talk about them. Using a Wittgensteinian approach, we argued more precisely that football, like any sport, may be understood as a form of life, and as such that it enables speakers to talk about it in quite specific ways, not least in the manner in which normative terms, such as fairness and bias, are used. Football thereby creates a metaphorical space, we suggest, in which there is a freedom to explore and play with language, and in particular normative language, even if that language-use is repressed in the wider political society. Using the example of the Iranian television programme Navad as a case study, we explore the ways in which talk about fairness in the context of football can develop and sustain a competence in the use of political and moral language-use even when that competence is under-threat elsewhere.     

The development and validation of a Fear of Death Scale based on the cognitive approach of Avicenna

ABSTRACT

The aim of this study was to develop a culturally sensitive approach assessment instrument that measures cognitive beliefs related to Iranian Muslim salient fear of death. This paper discusses the development and validation of Avicenna Fear of Death Scale (AFDS). The results of confirmatory factor analysis resulted in an instrument (AFDS) consisting of five cognitive concerns related to the fear of death including complete annihilation, severe pain of death, consequences of sins, interpersonal attachment, and attachment to estate. Twenty-two statements overall were offered using a Likert scale to measure related cognitive beliefs. Results from a convenience sample of 291 college students, showed the AFDS to have favourable psychometric properties (e.g., adequate reliability and validity). The total alpha coefficient was .85, suggesting that the items have relatively high internal consistency and the item-total correlation between .28 and .63 (p<.001) indicates that the items are discriminating well. Overall, results suggest that cross-cultural differences render a culturally sensitive approach to assessment and diagnosis essential, and therefore a culture-based scale like Avicenna AFDS might be fruitful extensions of the current death anxiety scales like Templer Death Anxiety Scale within the context of Iranian-Islamic culture. This diagnostic tool can help in the cognitive treatment of fear of death.
